Talisman

Carried by the Outer Sailor Guardians, the three Talisman hand each warrior a treasured arm. Sailor Uranus wields the Space Sword, Sailor Neptune the Deep Aqua Mirror, and Sailor Pluto the Garnet Orb. They surface in every account that reaches the Infinity arc, from the manga through the 90s anime, Crystal, and the Sera Myu musicals. The concept borrows from Japan's Imperial Regalia, the legendary sword, mirror, and jewel of an emperor's enthronement, treasures said to have come down from the sun goddess Amaterasu.

Within the manga and Crystal, the three treasures sing out together whenever their owners are gathered, first doing so at the Moon Castle in the wake of Queen Metalia's destruction of the Silver Millennium. That harmony woke Sailor Saturn, who joined the others and let her Silence Glaive fall to end whatever survived of the ruined kingdom. Generations later, Mamoru, Usagi, and the Inner Guardians are visited by premonitions demanding the treasures be reunited to set off an apocalypse, a vision Kaolinite shares without understanding. Every Outer Guardian receives her Talisman as she awakens to her strength. Brought together, they resonate to pour power into the Holy Grail of Sailor Moon, join to raise a barrier penning in Pharaoh 90, and sound once more to rouse Saturn in the modern age.

The animated telling sends the Death Busters chasing the treasures in rivalry with Uranus and Neptune, since the trio lay hidden within three unnamed individuals, each concealed in a Pure Heart Crystal. To find them, the villains loosed Daimons on any civilian they suspected, while the two Guardians moved in to test each guess. Eudial at last uncovered that two of the treasures dwelled inside Uranus and Neptune. The two extracted their own Pure Hearts, a deed that slew them and let the pair of treasures emerge, at which point Sailor Pluto came forward bearing the third. Once the fallen two were restored, the trio called up the Holy Grail, and Sailor Moon rose to her Super form for the very first time.

The three treasures rest respectively with Sailor Uranus, Sailor Neptune, and Sailor Pluto. Other members of both the Outer and Inner ranks carry signature arms of their own, among them the Mars Arrow, the Mercury Harp, the Silence Glaive, the Whip of Love, and the Leaves of Oak, though none of these sits at the story's core the way this trio does. In the Cloverway English dub of the 1990s anime, the trio went by the name Crystal Treasures.
